BGT24ATR22E6433XUMA1

Overview

The BGT24ATR22E6433XUMA1 is a highly integrated 24 GHz pulsed Doppler radar transceiver MMIC designed for automotive sensing applications. It operates within the 24.00 to 24.25 GHz ISM band and features two transmit (TX) channels and two receive (RX) channels. The device includes a fully integrated low phase noise voltage-controlled oscillator (VCO), medium power amplifier with variable output power, and an on-chip power and temperature sensor. Packaged in a PG-VQFN-32 leadless package, it supports angle of arrival detection and motion sensing capabilities.

Feature Summary

• Fully integrated low phase noise VCO for signal generation
• Dual TX and dual RX channel architecture for spatial processing
• On-chip power and temperature monitoring sensors
• Supports angle of arrival detection and velocity measurement

Applications

• Automotive kick sensors
• Hands-free trunk opening systems
• Gesture recognition interfaces
• Smart access control mechanisms

Procurement Notes

Verify component authenticity through authorized Infineon distributors or certified partners. Confirm that the specific ordering suffix matches the required package and tape/reel specifications. Ensure compliance with AEC-Q100 automotive qualification standards during procurement. Check for end-of-life status or recommended non-replacement notices before finalizing supply chain agreements.

Selection Notes

Select this transceiver for short-range automotive radar systems requiring precise motion and presence detection. The dual-channel configuration enables effective angle estimation compared to single-channel alternatives. Consider system-level integration requirements, as the device requires only an entry-level microcontroller for operation, reducing overall bill of materials costs and development complexity.

Part Context
